I too run FireFox in their latest write, on a 2013 lenovo (IBM).
It's weird entertainment, opening sites that recommend Chrome, MS and other browsers; there are few that won't run. I figure those are designed to phish info, I ain't playing that Homie. Nothing useful on the net that can't be found elsewhere, that will countercheck easily. I've been declared closet Luddite, correcting them as I'm merely wary.
